You will find the completion file under release/kafka. You can source it in
your terminal or drop it in /etc/bash_completion.d/. You have to set up
bash-completion too, which depends on your distribution of choice.

Currently completion is provided for five utilities:

kafka-topics

kafka-console-consumer / kafka-avro-console-consumer

kafka-console-producer / kafka-avro-console-producer

kafka-mirrormaker

kafka-acls

We provide completion for options, kafka configs and kafka properties.
Especially for kafka-topics if you set the --zookeeper switch, we try to
offer completion for topics as well.
